Zac Affleck is taking the blame for how he treated Jen Affleck. The two are going through a divorce while also getting ready for baby No. 4.

He shared a long statement on his Instagram Stories. In it, he admitted his words plus his actions were unacceptable. He said they hurt the people he is closest to.

He wrote that he has taken full responsibility for his behavior. "I deeply regret how my actions negatively affected Jen throughout our relationship," he added.

No bad blood

Things between them are better than they may look, according to reports. Sources say the pair talk well behind closed doors. They are said to be on very good terms with no hard feelings.

Not on the new show

Zac did not take part in filming the new "Mormon Wives" OC spinoff. He confirmed that in his post. He also said he has not seen a single episode.

He explained that the cameras rolled during a rough stretch for the couple. No matter how things are edited, he said, Jen is still the mother of his kids.

Zac said he has owned his mistakes plus apologized to Jen directly. He said he is working to be the best coparent he can be.

He added that the two speak privately every day. They are always trying to stay on great terms, he said.

Thinking of the kids

Jen is pregnant with their fourth baby. Zac said he does not want to put any extra pressure on her by accident.

He knows his children may one day read about all of this. If that day comes, he wants them to understand that their mom plus their dad adore them above all else.

The split

Jen filed for divorce in Utah on November 3. They had been married for seven years.

Their struggles have been part of "The Secret Lives of Mormon Wives." The couple split once before but got back together.
